The Report View window is included among the many new features of GeoTeric 2018.1, such as Validate and the Master Project. It can be used to rapidly send items in the 3D Scene to a plan view for PowerPoint or other reporting documents. The value of this tool is most evident when dealing with large data as no time needs to be spent waiting for data to be extracted all over again. Whatever is in the 3D Scene will be sent to the Report View.

GeoTeric’s Master Project functionality allows the user to transfer data from a Master Project containing all key data into a Client Project which can be worked on individually. It also allows for project items such as horizons and faults to be seamlessly transferred between Client Projects.

The Master Project will be available with the release of GeoTeric 2018.1.

With the upcoming release of GeoTeric 2018.1, a variety of enhancements to the Adaptive Interpretation tools will be added. This is in addition to a Master Project option, a Report View and the release of the Validate module.

One of the interpretation enhancements in GeoTeric 2018.1 will be the ability to edit horizons in the Base Map by polygon – either those picked previously in GeoTeric or newly picked in the Base Map. The polygons can be used to fill horizon interpretations or delete them.

GeoTeric’s Adaptive Fault Interpretation is a powerful data driven and interpreter guided method of structural interpretation. Since the Graph Theory algorithm is used by the Adaptive Interpretation System to generate data following results, not many fault sticks are required to generate an accurate fault plane in GeoTeric. This allows for an efficient method of interpretation.

As part of GeoTeric's Cognitive Interpretation workflow, Spectral Enhancement is an important Data Conditioning stage allowing the user to get the most out of post stack seismic data prior to the Reveal stage, especially when it comes to investigating thin beds. A variety of methods can be used to enhance the vertical resolution of seismic data using GeoTeric. This blog post will highlight one of the less commonly used methods discussed in McArdle and Paton (2014).

GeoTeric’s Adaptive Horizons tool allows the user to intuitively and interactively edit a tracked surface or interpretation. This is done by identifying the mis-pick in the interpretation, selecting the “3D edit” icon, and re-interpreting the line (we recommend using Piecewise Tracking). This will then update the tracked surface in the surrounding area. The tick-box enables “3D Edit Override”, so any interpreted lines will be removed or overwritten. This is useful when the interpreted lines have been incorrectly positioned by the user.

GeoTeric’s Adaptive Horizons have a variety of tracking and fill modes to allow the interpreter to extract a horizons surface in a fast and accurate way, while being cognitively intuitive. GeoTeric’s tracking modes are interactive as all the possible routes through the data are determined using Graph Theory, and can be previewed in both the 3D viewer and in the 2D Interpretation window. The Fill modes can be easily chosen in the Base Map window or in the 3D window if tracking on a probe.

As part of the Cognitive Interpretation workflow, GeoTeric’s new Adaptive Horizons use Regional Structural Awareness to create the fastest and most accurate 3D seismic interpretation. Any seismic, attribute or HSV colour blend volume can be used as a source for the Adaptive Horizons (which can be interpreted in both the 3D scene or using a 2D interpretation window), with different auto-track fill options ranging from Waveform, Amplitude, PDF and Graph Theory depending on the source data and objectives. A variety of tracking modes are also available: Full line, Piecewise and Manual, all with interactive previews due to the Regional Structural Awareness. More details on these and other options will be covered in the next blog post.

Spectral Enhancement is crucial process when analysing thin beds. The most common method to QC Spectral Enhancement is to use the slider in the Spectral Expression Tool. However, sometimes data quality can limit the true extent of enhancement that can be visualised, often characterised by washed out reflectors.

CMY Blending is a very powerful Cognitive Interpretation technique in GeoTeric that can be used to reveal faults and stratigraphic or carbonate features. In this example we will look at using Structurally Oriented Semblance on angle stack data from the Taranaki Basin, New Zealand. After conditioning the data (noise attenuation and spectral balancing) for all three angle stacks, we can create SO Semblance attributes. This can be done in the Fault Expression tool or also in the Batch Processor: Processes>Attributes>Edge Attributes>SO Semblance. For more information on edge attributes click here.
